9 # From Paul Eggert (2014-10-31):
11 # Unless otherwise specified, the source for data through 1990 is:
12 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
13 # San Diego: ACS Publications, Inc. (2003).
14 # Unfortunately this book contains many errors and cites no sources.
16 # Gwillim Law writes that a good source
17 # for recent time zone data is the International Air Transport
18 # Association's Standard Schedules Information Manual (IATA SSIM),
19 # published semiannually. Law sent in several helpful summaries
20 # of the IATA's data after 1990. Except where otherwise noted,
21 # IATA SSIM is the source for entries after 1990.
23 # Another source occasionally used is Edward W. Whitman, World Time Differences,
24 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
25 # I found in the UCLA library.
27 # For data circa 1899, a common source is:
28 # Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
29 # http://www.jstor.org/stable/1774359
31 # A reliable and entertaining source about time zones is
32 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
34 # Previous editions of this database used WAT, CAT, SAT, and EAT
35 # for +0:00 through +3:00, respectively,
36 # but Mark R V Murray reports that
37 # 'SAST' is the official abbreviation for +2:00 in the country of South Africa,
38 # 'CAT' is commonly used for +2:00 in countries north of South Africa, and
39 # 'WAT' is probably the best name for +1:00, as the common phrase for
40 # the area that includes Nigeria is "West Africa".
41 # He has heard of "Western Sahara Time" for +0:00 but can find no reference.
43 # To make things confusing, 'WAT' seems to have been used for -1:00 long ago;
44 # I'd guess that this was because people needed _some_ name for -1:00,
45 # and at the time, far west Africa was the only major land area in -1:00.
46 # This usage is now obsolete, as the last use of -1:00 on the African
47 # mainland seems to have been 1976 in Western Sahara.
49 # To summarize, the following abbreviations seem to have some currency:
50 # -1:00 WAT West Africa Time (no longer used)
51 # 0:00 GMT Greenwich Mean Time
52 # 2:00 CAT Central Africa Time
53 # 2:00 SAST South Africa Standard Time
54 # and Murray suggests the following abbreviation:
55 # 1:00 WAT West Africa Time
56 # I realize that this leads to 'WAT' being used for both -1:00 and 1:00
57 # for times before 1976, but this is the best I can think of
58 # until we get more information.
60 # I invented the following abbreviations; corrections are welcome!
61 # 2:00 WAST West Africa Summer Time
62 # 2:30 BEAT British East Africa Time (no longer used)
63 # 2:45 BEAUT British East Africa Unified Time (no longer used)
64 # 3:00 CAST Central Africa Summer Time (no longer used)
65 # 3:00 SAST South Africa Summer Time (no longer used)
66 # 3:00 EAT East Africa Time

231 # From Abdelrahman Hassan (2007-09-06):
232 # Due to the Hijri (lunar Islamic calendar) year being 11 days shorter
233 # than the year of the Gregorian calendar, Ramadan shifts earlier each
234 # year. This year it will be observed September 13 (September is quite
235 # hot in Egypt), and the idea is to make fasting easier for workers by
236 # shifting business hours one hour out of daytime heat. Consequently,
237 # unless discontinued, next DST may end Thursday 28 August 2008.

316 # From Paul Eggert (2014-06-04):
317 # Sarah El Deeb and Lee Keath of AP report that the Egyptian government says
318 # the change is because of blackouts in Cairo, even though Ahram Online (cited

323 # For now, guess that later spring and fall transitions will use

325 # 24:00 the last Thursday before Ramadan, and back to DST at 00:00 the
326 # first Friday after Ramadan. To implement this,
327 # transition dates for 2015 through 2037 were determined by running
328 # the following program under GNU Emacs 24.3, with the results integrated
329 # by hand into the table below. Ramadan again intrudes on the guessed

546 # http://www.lexpress.mu/display_article.php?news_id=111216
547 # (in French), Mauritius will start and end their DST a few days earlier
548 # than previously announced (2008-11-01 to 2009-03-31). The new start
549 # date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
550 # given, but it is probably at either 2 or 3 wall clock time).
552 # A little strange though, since the article says that they moved the date
553 # to align itself with Europe and USA which also change time on that date,
554 # but that means they have not paid attention to what happened in
555 # USA/Canada last year (DST ends first Sunday in November). I also wonder
556 # why that they end on a Friday, instead of aligning with Europe which
557 # changes two days later.
